地铁列车振动环境响应预测方法
Prediction Method for Subway Train-Induced Environmental Vibration Responses
摘要
Abstract
The empirical method used for predicting subway train-induced environmental vibration responses in China is easy to calculate,and it can quickly predict vibrations for many sensitive objects near subway lines.Nevertheless,it has the disadvantages of single output index and low prediction precision.With the help of computer simulation,analytical,semi-analytical and numerical method can be used to predict certain sensitive object.When predictions for more objects are needed,however,there are large workloads and longer calculation time.Moreover,the uncertainties of prediction precision and reliability also exist.In order to reduce prediction errors and decrease prediction uncertainties,the calibration method with both two positions of input and output based on in-situ measurements as well as the measured transfer function can help calibrate prediction model and validate prediction results.To improve prediction reliability,and to consider both prediction precision and efficiency,prediction zones should be distinguished according to the distances between sensitive objects and subway lines,different classifications should be defined according to the sensitivities of objects to environmental vibration impacts,and different prediction stages should be distinguished by different design stages.The existing prediction methods are suggested to be integrated,and the dynamic vibration response predictions are suggested to be performed by different zones,classifications and stages.Finally,it is suggested that the design stage-accompanied prediction and evaluation system for subway train-induced vibrations should be developed in future,which can predict vibrations for both whole subway lines and certain sensitive objects.关键词
